Abstract Introduction To assess the association between exposure to micafungin, other echinocandins, or azoles and the development of short-term liver injury (STLI) or long-term liver injury (LTLI) in patients with Child–Pugh B or C liver disease. Methods Multicenter case–control study of patients with Child–Pugh B or C liver disease who received antifungals (AF) for ≥ 72 h (May 2009–May 2015) in six Spanish and Italian hospitals. All micafungin patients were randomly matched with one patient who received another echinocandin and with one patient who received azole treatment. Primary outcome was development of STLI or LTLI (development of any type of liver tumor during the follow-up period). Results Of 2335 patients with chronic liver disease admitted to the six centers, 20 (0.85%) were found to have Child–Pugh B or C liver disease and received micafungin for ≥ 72 h. During AF treatment, the frequency of STLI was 10% in each group. Most cases of STLI were asymptomatic, and AFs had to be switched to another class of AF in only two patients (one micafungin and one azole). No patients developed acute liver insufficiency, were admitted to the ICU, or had to undergo transplantation. Follow-up data (median of 1.3 years) were available for 30 patients. LTLI was observed in only one patient, who had previously received treatment with azoles. Conclusions Our study suggests that the administration of micafungin to patients with end-stage liver disease does not imply a higher risk of developing STLI or LTLI.

Abstract Introduction We evaluated the diagnostic reliability of serum polymerase chain reaction (PCR) versus blood culture, abdominal fluid or both (composite measure) in patients receiving empirical antifungal treatment for suspected invasive candidiasis. Methods This observational, prospective, non-interventional, multicentre study in Spain enrolled 176 critically ill patients admitted to the intensive care unit. Separate blood samples for culture and serum PCR were taken before the start of antifungal therapy. Patient assessment was performed according to each site’s usual clinical practice. The primary end point was concordance between serum PCR and blood culture. Secondary end points were concordance between serum PCR and a positive abdominal fluid sample or the composite measure. Quality indices included sensitivity, specificity, positive/negative predictive values (PPV/NPV) and kappa indices. Results Among 175 evaluable patients, rates of Candida detection were similar for serum PCR (n = 16/175, 9.1%) versus blood culture (n = 14/175, 8.0%). Quality indices for serum PCR relative to blood culture were: sensitivity 21.4%; specificity 91.9%; PPV 18.8%; NPV 93.1%; kappa index 0.125. Thirty-two abdominal fluid samples were positive. Quality indices for serum PCR versus abdominal fluid were: sensitivity 31.3%; specificity 83.0%; PPV 15.6%; NPV 92.3%; kappa index 0.100. Quality indices for serum PCR versus the composite measure were: sensitivity 15.8%; specificity 92.7%; PPV 37.5%; NPV 79.9%; kappa index 0.107. Conclusion The sensitivity of serum PCR for Candida detection was low and the rate of concordance was low between serum PCR and the other diagnostic techniques used to identify Candida infections. Hospital-based diagnostic tests need optimising to improve outcomes in patients with suspected invasive candidiasis. Funding Astellas Pharma Inc.
